CVE-2026-129452DrayTek Vigor2960 command injection

Why this priority: High severity, with no exploitation signal yet.
Published · Updated · NVD status: Deferred
What it is
Input ends up inside a command the software runs, so an attacker can add commands of their own. Input is passed to another component as instructions rather than data.
How it is reached
An attacker can exploit it over the network, with an administrator account, and nobody has to click anything.
What an attacker gains
A successful attack can read the data it protects, change data or behaviour and take it offline. In practice, this kind of flaw lets an attacker run commands or code with the privileges of the affected service. The damage can spread past the vulnerable component into others.
Is it being exploited?
There is no public report of exploitation yet.
What to do
- Upgrade DrayTek Vigor2960 to 1.5.1.7 or later.
- Until it is patched, review who holds accounts that can reach it.
Description from NVD
A vulnerability has been found in DrayTek Vigor2960 1.5.1.6. This vulnerability affects the function set_table of the file /cgi-bin/mainfunction.cgi. Such manipulation of the argument jsondata leads to command injection. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. Upgrading to version 1.5.1.7 is able to resolve this issue. It is suggested to upgrade the affected component. The vendor recommends: "1.5.1.6 isn't the latest version of 2960, the latest version fixes many security issues. And we have another one in our release plan which should solve the issues reported."
What this means for your architecture.
A CVE names a product. Whether it matters depends on where that product sits in your systems: what reaches it, which trust boundary it guards and what it can reach once compromised. Veriom maps your components, their relationships and your trust boundaries from your code, cloud and delivery evidence, so you can see where a component like this sits. The radar itself does not look at your systems.
Components it touches
- Network edge devices: VPNs, firewalls, routers and gateways. They sit between the internet and internal networks, so a flaw in one is often the first step into everything behind it.
- Operating systems on servers, workstations or devices. Everything on the host inherits the flaw.
- Application servers and the hosts they run on. The flaw sits between untrusted input and code or command execution.
- Template engines. The flaw sits between untrusted input and code or command execution.
Trust boundaries in play
- Authenticated network access. An account is needed, so exposure follows who can sign in: customers, partners or staff.
- Isolation between components. The impact crosses out of the vulnerable component into others it should be isolated from.
- Between untrusted input and code or command execution. An attacker who crosses it can run commands or code with the privileges of the affected service.
Questions to answer about your own systems
- Where does DrayTek Vigor2960 run in your systems, and at which version?
- Which of those instances can be reached from the internet or partner networks?
- What can it reach once compromised: which data stores, secrets and services?
